The game consists of working your way through three different boxing circuits for a chance at a bout with Mike Tyson. Along the way you'll encounter many colorful characters, some of which you'll see in a rematch if you beat them. The fights get progressively harder, and passwords are given after each circuit so you don't have to complete the game in one sitting. Your record of wins, losses and KOs is tracked through any single play session, and if you use a code to jump to a circuit you'll start with a perfect record.
